7 Specification of Letters Patent.

Patented May 20, 1919.

Application filed January 14, 1919. Serial No. 271,102.

To all whom it may concern:

Be it known that I, FRANCIS O. KAEPPLER, a citizen of Germany, residing at Los Angeles, in the county of Los Angeles and State'of California,have invented new and useful Improvements in Curtain-Windows, of which the following is a. specification.

My object is to make an improved curtain window and my invention consists of the novel features shown, described and claimed.

The leading feature of my invention is the use of a heavy fiat plate of glass having a groove in its edge all the way around and the attachment of the glass to the curtain without any visible frame.

Figure 1 is a fragmentary elevation of a curtain having a window embodying the principles of my invention, parts being shown in section.

Fig. 2 is an enlarged fragmentary sectional detail as on the line 22 of Fig. 1.

Figs. 3, 4, and 5 are sectional details analogous to Fig. 2 and showing modified constructions.

Referring to the drawing in detail, the glass plate 1 has a continuous curved edge 2 and a V shaped groove 3 formed in edge 2 all the way around. The glass plate shown is oval in plan, but it is obvious that it may be circular or any other desired form. The outer sheet 4 of the curtain may be pantasote or any other usual curtain material and the inner section 5 of the curtain may be a cheaper material. The sections 4 and 5 are brought together and openings 6 are cut in the sections 4 and 5, the openings being somewhat smaller than the edge 2 of the lass. g Pieces 7 of celluloid sheets are placed between the sections a and 5 around the openings and stitching 8 is applied to connect the edges of the sections A and 5 and celluloid plate sheets firmly together. The celluloid sheets 7 have one or more breaks so that the glass plate 1 may be snapped into the openings, then cords 9 and 10 are wound around the glass against the seam 8 and between the sections 4 and 5 and each side of the celluloid plates 7 so as to draw the edges of the material firmly into the groove 3. Shellac or the like may be applied to the cords 9 and 10 so as to set the cords and hold them from stretching. The glass plate 1 is of a proper thickness to receive a good groove 3 and so that when the plate has been applied to the curtain, as shown in Fig. 2, the outer faces of the curtain sections 4 and 5 are practically flush with the faces of the glass and when the window is thus constructed as shown in Fig. 1, there is no visible frame for the glass'plate.

In Fig. 3 I have shown the glass plate 1 mounted in the curtain, comprising the sections 4 and 5 without the use of the celluloid sheets 7. The celluloid sheets as shown in Figs. 1 and 2 serve to make a hard edge to extend into the groove 3, but it is obvious that the celluloid may be omitted, especially with the light plate of cheaper construction.

In Fig. 4: I have shown the glass plate 1 mounted in the curtain with the section 4 of curtain material and the sheets 7 of celluloid. The inner edge of the pant-asote is brought around the inner edges of the sheet 7 and secured in place by stitching 11. In this construction, the sheets 7 will make the appearance of a filame around the glass When seen from the side and this construction is suitable where the curtain is made of one section of material.

In Fig. 5 I have shown the glass plate 1 mounted in the curtain composed of a single section of material 4:. The inner edge of the material is turned inwardly and backwardly to fit in the groove 3 and the cords 12 are wound against this material. This will make a good construction where the curtain and glass are to be small and light and where it is only desired to have one thickness of curtain material.

Various changes may be made without departing from the spirit of my invention as claimed.

I claim.

1. A curtain having a window opening, a glass plate having a groove in its edge with the curtain material extending into the groove, and means for holding the parts together.

2. A curtain having a window opening, a glass plate having a groove in its edge with the curtain material extending into the groove, and cords wrapped in place to hold the curtain material in the groove.

8. A curtain having a window opening, a glass plate having a groove in its edge with the curtain material extending into the groove, means for forming a hard edge on the curtain material in the groove, and means for holding the hard edge in the groove.

4. A curtain having a window opening; a

glass plate provided with a longitudinal groove in its edge with the curtain material extending into the groove; and means engaging said groove for securing the curtain material to the glass plate.

5. A curtain having a window opening; a glass plate having a groove extending along its entire edge with the curtain material 6X- tending into the groove; and flexible means engaging said curtain material and disposed within said groove for holding the curtain material and the glass plate together.

6. A curtain having a Window opening; a glass plate having a groove extending along its entire edge and V-shaped in cross sectlon and with the curtain material extending into the groove; and flexible means engaging said curtain material and disposed within said groove for holding the curtain material and the glass plate together.

In testimony whereof I have signed my name to this specification.
